Kaliningrad is former Koenigsberg, the city of East Prussia annexed by the USSR in 1945. A huge number of architectural monuments such as castles, defensive forts, bunkers and fortresses have remained there from the ancient times. It is surrounded by the borders of other states, so it’s a perfect starting place for your travels. The city is located on the shores of the Baltic Sea and invites you to a leisurely rest on the beach. There is a great chance to find an amber stone at the sea. It is the site of the Kaliningrad amber plant – 90 percent of the world’s amber comes from this region.
